PLEASE READ BEFORE PROCEEDING
PerTronie© thanks you for choosing a Patriot Exhaust Product. To realize the potential of Patriot’s engineering and excellent fit, Please Read and Understand these instructions completely prior to starting the installation.
Check that you received all the parts listed on the parts list, if you have any concerns, please contact PerTronix before continuing. Headers will have the part number stamped in the flange.
Work Smart — Work Safe! Most Header and Exhaust Installation are best performed on a lift. If a lift is not available, raise the vehicle and support on quality Jack Stands on level ground. Do not rely on a jack!
Many factors affect he installation of exhaust headers, including worn or aftermarket motor mounts, previous accident damage, aftermarket cylinder heads that may have relocated port or spark plug locations, suspension and steering changes, sagging of original unibody structures due to age.
Coating Notes: Coatings can be marred during installation if you are not careful. If you are breaking in a new motor, the extreme heat can alter the appearance of the coating and this is not a warranty issue. We recommend breaking in new motors with stock manifolds or an old set of headers.
We use sealing beads on all our headers. The raised bead creates a better seal virtually eliminating leaks if installed properly. It is important to install all header bolts lightly snug and then tighten to factory torque specs starting in the center and working outward.
Before starting, allow the vehicle to cool, disconnect the battery, and spray a penetrating oil on all hardware and fittings that will need to be removed. Once you remove your manifold, clean the sealing surface on the head of any old gasket debris or carbon build up.

DISASSEMBLY

1. Remove bolts attaching head pipes stock manifolds, then remove the stock manifolds.
2. Remove the Clutch Linkage on Manual transmission equipped cars.
3. Remove the Oil Filter.
4. Remove any remaining gasket or carbon deposits from the head surface.

INSTALLATION

1. Starting on the Driver’s side, slip the header roughly into position from the bottom. You will have to move the stock head pipes out of the way if you haven’t already done so.
2. Using the supplied 3/8-16X3/4” Header bolts, slip the gasket in place and start header bolts.Leave bolts loose at this time. Some Original Pontiac Heads do NOT have a bolt hole at one end. This MUST be drilled and tapped to ensure good gasket sealing.
3. Re-install clutch linkage.
4. Tighten all header bolts evenly starting in the center.
5. Passenger side, slip the header roughly into position from the bottom. You will have to move the stock head pipes out of the way if you haven’t already done so.

7. Replace the Oil Filter.
8. Tighten all header bolts evenly starting in the center.
9. If reusing the existing exhaust system cut and modify as necessary to connect to the headers using the supplied Patriot Reducers.
10. Connect the negative battery cable.

IMPORTANT CHECK LIST

• Be sure that all brake lines, transmission lines, and fuel lines are clear of headers and/or connector pipes.
• All spark plug wires, battery cables, or other electrical components should be clear of headers and/or connector pipes.
• If dipstick tube was removed, make sure it is installed properly and that the dipstick has been replaced.
• Double-check the tightness of all bolts including brackets and accessories.

START THE ENGINE
Start the engine and allow it to warm up to operating temperature. Check for any unusual noises or exhaust leaks. If everything is OK, stop the engine and tighten all bolts while the engine is still warm.
